AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
This work is focused on the numerical analysis of pollutant formation in an aviation gas turbine engine at different values of power setting. The analysis is conducted on the basis of a comprehensive approach treating the reactor net model for description ...
Traffic is believed to organize itself by minimizing user’s travel cost (travel time is used as cost very often). Almost all the analytical and numerical work in the last 50 years has concentrated on travel cost and the assumption that costs are always an ...
The thermo-environomic assessment of the industrial production of ammonia has been investigated in this project. Thermodynamic models for the ammonia synthesis were developed on the flowsheeting software Vali based on the techniques used at LENI. Several p ...
An exergy and environmental comparison between the fuel production routes for Brazilian transportation sector, including fossil fuels (natural gas, oil-derived products and hydrogen), biofuels (ethanol and biodiesel) and electricity is performed, and the p ...
Methane can be an alternative fuel for vehicular usage provided that new porous materials are developed for its efficient adsorption-based storage. Herein, we search for materials for this application within the family of diamond analogues. We used density ...
Hydrogen is often regarded as a viable clean burning alternative to our current petroleum based fuel sources as a result of its high gravimetric energy d. and renewable nature. Furthermore, H2 has received significant attention as a transportation fuel. A ...
This paper formulates the problem of aircraft conflict avoidance as a multiphase mixed-integer optimal control problem. In order to find optimal maneuvers, accurate models of aircraft nonlinear dynamics and flight envelop constraints are used. Wind forecas ...
The conversion of lignocellulosic biomass to ethanol is currently one of the most popular options for sustainable production of transportation fuel from renewable resources. Due to the resistance of lignin compounds to biological degradation and the import ...
The purpose of this study is to evaluate, in terms of process integration, the centralised and decentralised pre-treatment of lignocellulosic biomass for its thermo-chemical conversion into liquid fuels through gasification and Fischer-Tropsch (F-T) synthe ...
The fabrication, modeling and testing of a pyroMEMS balloon actuators are presented herein. A foil-level fabrication method was developed, integrating nickel-plated, inkjet-printed igniters capable of generating >200 degrees C for similar to 1 s-sufficient ...
